[Previous][Table of Contents][Next]

Nationally notifiable since 1924

1.0 National Notification

Only confirmed cases of disease should be notified.

2.0 Type of Surveillance

Routine case-by-case notification to the federal level

3.0 Case Classification

3.1 Confirmed case—Genital Infections

Laboratory evidence of infection in genitourinary specimens:

• detection of Neisseria gonorrhoeae by culture
  OR
• detection of N. gonorrhoeae nucleic acid

3.2 Confirmed Case—Extra-genital infections

Laboratory confirmation of infection from pharynx, rectum, joint, conjunctiva, blood and other extra-genital sites:

• detection of N. gonorrhoeae by culture
  OR
• detection of N. gonorrhoeae nucleic acid

3.3 Confirmed Case—Perinatally Acquired Infections

Laboratory confirmation of infection from a neonate in the first four weeks of life leading to the diagnosis of gonococcal conjunctivitis, scalp abscess, vaginitis, bacteremia, arthritis, meningitis or endocarditis:

• detection of N. gonorrhoeae by culture
  OR
• detection of N. gonorrhoeae nucleic acid

4.0 Laboratory Comments

Further strain characterization is indicated for epidemiologic, public health and control purposes.

A positive test for Gram-negative intracellular diplococci in symptomatic males with urethral discharge provides a presumptive diagnosis for gonorrhea in men.

5.0 Clinical Evidence

6.0 ICD Code(s)

6.1 ICD-10 Code(s)

A54.0, A54.1, A54.2, A54.5, A54.6 , A54.9

7.0 Type of International Reporting

8.0 Comments

Each case classification is mutually exclusive.

Individuals with more than one site of infection concurrently may fall under more than one case classification but will be counted as one case with multiple sites of infection identified, to avoid duplicate counting of cases.
